One of the best things about systems is that they can be easily reduced to a graphical representation. You do not need to read about the processes and logically assemble them in your mind; you can look at a flowchart and "see" how the whole thing operates. A good flowchart is worth several times its weight in gold in the world of systems. It clarifies the system. It communicates processes to those who need to understand them. It provides an instantly interpretable and adjustable road map that allows for systems review and improvement.
